Reality TV star Khloe Kardashian has made it publicly known that she misses her younger brother Rob Kardashian.
The "Kocktails with Khloe" host posted on Twitter a throwback photograph featuring Rob kissing her along with a heartfelt message for him, reports aceshowbiz.com.
"It's simple... I miss you," she wrote.
The 31-year-old star also added three crying face emojis to emphasise her feelings.
Shortly after the image was posted, Kourtney Kardashian replied to her younger sister's tweet. She wrote, "True Love."
Khloe's post came after Rob's new girlfriend Blac Chyna shared some photographs of her and Rob on Snapchat.
The couple was then spotted packing on the public display of affection as they strutted the streets of California on Thursday.
Rob and his star sisters have been at war ever since he began dating the 27-year-old model in January. A source said that his sisters were "livid" about his relationship.
"All the sisters are united and think Rob is being disloyal," the source said. "They want him to be happy, but they're just so over the whole thing."
